Dark-field microscopy has been used since the early 20th century to observe living, unstained cells and microorganisms. Specimens are brightly lit against a dark background to provide the contrast needed to study samples in solutions or natural aquatic environments such as pond water. This article looks at what dark-field microscopy is and its applications.
